You're in the clear tonight and through tomorrow morning. Tomorrow afternoon brings a 15-20% chance of a quick shower or two between 2 and 5 PM — nothing organized, but stay aware — then dries out again by evening. By midweek, a slightly better rain chance develops Tuesday through Thursday, with Wednesday looking like the best bet for a few tenths of rain, though confidence is low and most of us will stay dry.

Why This Forecast

NWS FFC Analysis

Issued Jun 28, 8:50 PM

Tonight you'll see temps drop to the mid-70s under mostly clear skies, but don't expect much relief. Monday brings the real heat—a Heat Advisory is in effect from noon to 8 PM, with highs near 95°F and heat index values pushing past 105°F. There's a 30% chance of scattered showers and thunderstorms Monday afternoon into evening, mainly across central and eastern Georgia including your area, but nothing significant is expected. Monday night those storms clear out and temps only fall back to the mid-70s.

What's driving all this is a big ridge of high pressure, that's essentially a dome of sinking air that suppresses weather systems, sitting over the Gulf and pushing eastward into Georgia. With that ridge in place, you get two competing effects: strong daytime heating that stacks the deck for afternoon thunderstorms, but also strong "inhibition"—a capping layer of warm air aloft that makes it harder for storms to actually fire up. The jet stream, that river of fast air 30,000 feet up, is positioned in a way that's allowing this heat dome to linger over the Southeast for days. Moisture is also high, so even when it's not storming, the air feels thick and oppressive.

Look for this pattern to stick around through the week. Highs stay in the mid-90s daily with lows only dipping to the low-to-mid 70s at night, so you won't get much cooling relief. Every afternoon has an isolated to scattered thunderstorm chance, though most days won't see much rain. The real story through Wednesday and beyond is the heat index—expect values over 100°F most days and 105°F or higher in some spots. That's the kind of setup where heat safety matters, especially if you're working outdoors or exercising.
